DETACHABLE SHOE-HEEL.

.To all 'who/m it may concern.'

Be it known that l, FRANK G. MOCOLLUM, a citizen of the United States ofAmerica, and a resident of Cambridge, in the county of Middlesex andState of Massachusetts, have invented certain new and usefulImprovenients in Detachable Shoe-Heels, of which the following is aspecification.

rlhis invention relates to detachable heels for boots and shoes and hasfor its object the provision of a means whereby a composite heel may beattached to or detached from the shoe and the various heel lifts variedat the will of the operator.

The invention consists in certain novel features of construction andarrangement of parts which will be readily understood by reference tothe description of the drawings and to the claims hereinafter given.

Uf the drawings: Figure 1 represents an elevation of a portion of therear part of a shoe showing a heel embodying the features of thisinvention applied thereto, a portion of the inclosing band being brokenaway. Fig. 2 represents an inverted plan of the heel part of the soleshowing a permanent lift secured thereto. Fig. 3 represents a plan ofthe outer detachable heel lift. Fig. 4; represents a plan of one of thefilling members. Fig. 5 represents a transverse section of a portion ofthe shoe, the cutting plane being on line 5-5 on Fig. 1. Fig. 6represents a transverse section of the same, the cutting plane being online 6-6 on Fig. 1. Fig. 7 represents a plan of the inclosing band, aportion of the same being shown in section, and Fig. 8 represents one ofthe clips used to retain the various lifts together.

Similar characters designate like parts throughout the several figuresof the drawings.

ln the drawings, 10 represents a sole and 11 an upper of a shoe of anywell-known construction to which is permanently secured the heel lift12. This heel lift 12 is provided with a plurality of shouldered memberssuch as the headed pins 13 and the top or outer heel lift 14 is providedwith similar shouldered members such as the headed pins 15. When theheel is to be made up and applied to the shoe a plurality of fillingmembers 16 are interposed between the lifts l2 and lll. These fillingmembers may be made of any suitable material, as,

for instance, of leather, as indicated in Fig. t, or of cork, asindicated at 16a in Fig. 6, or of rubber, as indicated at 16b in Fig. 6.

lVhen the necessary number of lillin g members have beeninterposedbetween the lifts 12 and 14:, the clips 17 are placed in position withthe slotted ends 18 straddling the` headed pins 13 and 15 of the top andbottom lifts 12 and 111 respectively, thus preventing the lifts frombecoming separated. rlhese clips 17 are made of flexible metalsuliiciently thin to permit an ordinary amount of spring. Both of thefilling members of cork and rubber are suiiiciently yielding to giveconsiderable spring while, when corlr is used, the heel is considerablylightcned.

ln order to retain the clips 17 in position and prevent lateraldisplacement an inclosing band 19 is provided, said band having inwardlyextending ears 2O which project into the heel above the upper fillingmember 16a so that the band is properly positioned, the ends of thisband being provided with a suitable locking device 21 which connects theends together and retains the band in position when the heel is made up.This band 19 not only prevents the displacement of the elias 17 and theseparation of the various lifts but it also covers up the edges of thefilling members which may be cut out by hand by the wearer and leftunnished. The band 19 is made of flexible metal which yields under theweight of the wearer of the shoe and thus gives a certain amount ofspring to the heel when in use.

lt is obvious that by such a construction as is herein set forththe heelmay be readily altered by the wearer to suit various conditions ofweather.

Should the outer lift when made of leather become worn on one side theseouter lifts of the two shoes may be interchanged so that the lifts willbe worn down evenly and the wearer may also lreep on hand an outer liftmade of rubber and replace the outer lift of leather with a rubber liftwhen desired.

As the filling members are hidden from View by the band 19 they may becut out roughly from any suitable material by the wearer and dispensewith the necessity of taking the shoes to a repairer, thus avoiding thedelay which would naturally ensue.

tween said lifts; and a plurality ot' clips each extending from ashouldered member on one lift to a shouldered member on the other lift.

2. The combination with the sole of a boot or shoe; of a heel liftpermanently secured thereto and provided with members having headsforming shoulders a slight distance from the face of said lift; a secondlift also provided with members having heads forming shoulde-rs a slightdistance from the face of said lift; a filling member interposed betweensaid lit'ts; a plurality of clips each extending from a shoulderedmember on one lift to a shouldered member on the other lift; and a thinyielding metallic band surrounding said filling member and retainingsaid clips in position.

V3. rlChe combination with the sole of a boot or shoe; of a heel liftpermanently secured thereto and provided with members having headsforming shoulders a slight distance from the tace of said lift; a secondlift also provided with members having heads lorming shoulders a slightdistance from the tace of said lift; a filling member interposed betweensaid lifts; a plurality of clips each extending from a shouldered memberon one lift to a shouldered member on the other lift; and a thinyielding metallic band surrounding said iilling member and retainingsaid clips in position., the ends of said band being provided with meansfor locking said ends together.

4. The combination with the sole of a boot or shoe; of a heel liftpermanently secured thereto and provided with members having headsforming shoulders a slight distance from the face of said lift; a secondliit also provided with members having` heads forming shoulders a slightdistance from the face ot' said lift; a iilling member interposedbetween said lifts; a plurality of clips each extending from ashouldered member on one lift to a shouldered member on the other lift;and a thin yielding metallic band surrounding said iilling member andretaining said clips in position, one end ot said band being providedwith a spring tongue adapted to extend into an opening in the other endof said band.

5. The combination with the sole oi a boot or shoe; of a heel liftpermanently .secured thereto and provided with headed pins; a. secondlitt also provided with headed pins; a tilling member interposed betweensaid lifts; and a plurality ot' removable clips extending from one setof headed pins on one lift to the other set of headed pins on the otherlift.

6. The combination with the sole oi a boot or shoe; oi a heel littpermanently secured thereto and provided with headed pins; the, heads ofwhich are at a slight distance from said lift; a second lift alsoprovided with headed pins similarly disposed; a filling memberinterposed between said lifts; and a plurality of removable clips, theends ol which are provided with slots adapted to straddle said pins andlock the various lifts together.
